MEANS FOR CATCI-IING AND BESTURING FLUID-LEAKAGE.

Specification of Letters Patent. Patnted Sept, i3, 11921.

Application filed Januaryl, 1920. VSerial No. 355,342.

To all whom it may concern:

Be it known that I, FRANK E. PAYNE, a citizen of the United States, residing at Glencoe, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Means for Catching and Restoring Fluid-Leakage, of which the following is a specification.

My invention relates to improvements in means for catching and restoring fluid leakage. It is particularly adapted for use in connection with the cooling systems for in ternal combustion engines.

The object of the invention is to prevent loss of liquid due to leakage from pumps and other fluid containers.

In carrying out my invention I provide suitable receptacles for catching the liquid which may leak through stuiiing boxes, such as are used on pumps, and returning said liquid to the system. Y

In the accompanying drawings AI have illustrated somewhat diagrammatically one embodiment of the invention.

The engine l may be an automobile engine, aeroplane engine, or other internal combustion engine, and is provided with a cooling system comprising the radiator 2,V pipe 3 leading from the radiator to the pump 4, pipe 5, which carries the water from the pump to the engine jacket and the return pipe 6 through which the heated water is returned to the reservoir in the upper part of the radiator.

The pump 4 may be of any suitable construction `and is not illustrated in detail herein. It is provided with the usual stufling boxes 7, 7 through which there is a certain leakage of water or other cooling liquid. In order to catch this liquid, I provide suitable cups or receptacles 8, 8, beneath said stufling boxes. A small pipe 9 leads from the bottom of each receptacle, said pipes preferably merging into a single pipe and terminating in the reservoir above the radiator preferably somewhat above the water line. The upper end of the pipe constitutes an injector 10. A return flow of the water from the injector into the tube 9 is prevented by a ball valve 11. An additional small pipe 12 leads from the pump outlet to said injector whereupon a fine stream of water at fairly high velocity is delivered by said pipe producing an injector action which draws the water from the cups 8 through-the pipe 9 delivering the same to the radiator. The

thermore, said discharge end is curved to deliver the liquid downwardly thereby further insuring against a reverse flow of liquid therethrough.

Although the receptacles 8 are shown as located beneath the stuffing boxes of the pump, it is obvious that they may be located elsewhere to catch whatever liquid may leak from the cooling system. The inventionis particularly adapted for use with aeroplane engines or automobile engines where it is not convenient to replace the water supply at frequent intervals. However, it is not limited to such use.

1. In combination with a fluid cooling system of an internal combustion engine, means for collecting the fluid leakage from said system and means operable against the force of gravity for restoring said leakage to said system.

2; In combination with the water cooling system of an internal combustion engine comprising a pump, radiator, and connections therebetween, a leakage catch basin, and means for injecting the contents of said catch basin into the cooling system.

3. In combination with a water cooling system of an internal combustion engine comprising a pump, radiator, and suitable yconnections therebetween, catch basins suitably located to catch the leakage from said cooling system, drain pipes leading from said catch basins, said drain pipes uniting in one pipe at a suitable point, said pipe extending to a point in the radiator above the water line, a check valve in said pipe, said pipe having its upper end arranged to discharge downwardly, and means for vdrawing the water through the drain pipes from said catch basins. j

4. The combination with a radiator, pump, stufling boxes therefor, pipes and other parts ioo of a water-cooling system of an internal comv bustion engine, catch basins beneath said stuffing boxes, a drain pipe leading from said lcatch basins in said drain pipe terminating in the radiator above the water line, a pipe leading from the outlet of said pump to said drain pipe, and means for preventing the water from said outlet pipe from flowing downwardly through said drain pipe.

5. In combination With the Water cooling system of an internal combustion engine, said system comprising a radiator, pump, and conduits, of catch basins -forming part of the pump structure, drain pipes leading therefrom, said drain pipes uniting in a single drain pipe extending into the upper part of the radiator above the Water line and terminating in a downwardly turned bend, a check valve formed in said drain pipe beneath said bend, and an injector pipe leading from said pump to said drain pipe and joined thereto at a point between said check valve and said bend. i

6. In combination With the Water cooling my name.

7. 'Ihe combination in a circulating luid i system of a pump, a receptacle to catch fluid leakage 'from said system, and an injector associated with the pressure side of said pump for restoring said Vleakage to said system. Y

In testimony whereof, I have subscribed FRANK E. PAYNE.
